An App ID is two-part string that identifies one or more apps from a single development team in a provisioning profile. There are two types of App IDs: an explicit App ID (used for a single app) and a wildcard App ID (used for a set of apps).
An explicit App ID contains the full path of a bundle ID. A wildcard App ID contains an asterisk as the last part of its bundle ID search string. Note: An explicit App ID is required to submit your app to App Store Connect and to use certain services.
